C 680 BL

Table Microphone

Description

The C 680 BL is a boundary layer condenser microphone
with a cardioid pattern intended for table use, lecterns, and
houses of worship. The transducer is internally shock
mounted for immunity to impacts on the mounting surface.
The microphone is provided with a roll of non-staining
double-sided adhesive for positive mounting of the
microphone to a table or other flat architectural detail.

The microphone has a sensitivity of 23 mV/Pa and can
directly drive many microphone input stages with limited gain
reserve. The microphone is phantom powered over the range
from 9 to 52 volts dc.
